    There are several errors in your example on page 45 and I have attached two computations one with the Bygrave and one with a calculator. 

    At the beginning you exhanged starting latitude with destination latitude The your calculation of the Az and Hc went wrong somewhere.

    I notice that you use my notation for 90 degrees as 89-60 to make subtraction easier but you might like to mention that as an introduction.

    That is the only part of your manual that i have had the chance to look at.
